PHP Webform User change password field in csv flat file

[pachanga1]

Hello,

I need some programming help ...been working on this for over a month and can't get it to work...I have a signup form which allows a user to save their username,password, address, email, phone.... to a flat file (csv).  I was wondering if someone can help me to program a script that will allow the user to change any of his information...reset a password, change phone...etc...your help is greatly appreciated! This has to be done using a flat file..thx!

 

the current script is:

 

<?php

 

session_start();

// functions

$ufilename = "userfile.txt";

//$email = $_POST['email'];

//$address = $_POST['address'];

$phone = $_POST['phone'];

$favcolor = $_POST['favcolor'];

$_SESSION["sname"] = $uid;

$_SESSION["semail"] = $email;

$_SESSION["saddress"] = $address;

$_SESSION["sphone"] = $phone;

$_SESSION["sfavcolor"] = $favcolor;

 

 

 

function saveCookie($username) {

    $cname = "userdata";

    $cvalue = $username;

    $exp = time()+60*60*24*30*12;      // one year

    setcookie($cname,$cvalue,$exp);     

}

 

function validateUser($userid, $pwd) {

    // does file exist?

    $retval = -1;

    // return values are -1 no user/pass

    // 0 means good user but bad pass

    // 1 means both ok

    global $ufilename;

 

    if( file_exists($ufilename)) {

 

        $filerecs = split("\n",file_get_contents($ufilename));

        $userpwd = crypt($userid,$pwd);

        // print "Userpwd is $userpwd";

       

        foreach ($filerecs as $line ) {

            // print "Line is $line";

            $recs = explode(",",$line);

           

            if( $recs[0]==$userid) {

                $retval = 0;

                if( $recs[1]==$userpwd) {

                    $retval = 1;

                }

                break;

            }

        }

        return $retval;

}

else {

    die("Read error");

}

}

 

function findUser($uid) {

    global $ufilename;

    if( file_exists($ufilename)) {

        $filerecs = split("\n",file_get_contents($ufilename));

        foreach ($filerecs as $line ) {

            // print "Line is $line";

            $recs = explode(",",$line);

            if( $recs[0]==$uid) return TRUE;

        }

        return FALSE;

    }

    else return FALSE;

}

 

function createUser($uid, $pwd, $email, $address, $phone, $favcolor) {

    // open file for append

    global $ufilename;

   

    $fp = fopen($ufilename,"a");

    $userstring = $uid.",".crypt($uid,$pwd)."," .$email."," .$address."," .$phone.",".$favcolor."\n";

    fwrite($fp,$userstring);

    fclose($fp);

}

 

///////////////////////////////////////////////////

 

if( $_POST['newuser']==TRUE) {

    if( findUser($_POST['uid'] )==FALSE ) {

        createUser( $_POST['uid'], $_POST['pwd'], $_POST['email'], $_POST['address'], $_POST['phone'], $_POST['favcolor']);

        header("Location: access.php");

    }

    else

        header("Location: resetpassword.html");

}

 

$valuser = validateUser( $_POST['uid'], $_POST['pwd']);

 

if( $valuser==1) {

 

    if( isset($_POST['usave']) && $_POST['usave']==TRUE ) {

            saveCookie( $_POST['uid'] );

    }

    include_once 'tokenpage.php';

    $_SESSION['token'] = $tokendata;

    header("Location: GetData.php");   

}

 

if( $valuser==0) header("Location: resetpassword.html");

 

// leave

if( $valuser==-1) header("Location: BadLogin.html");

 

 

?>

I don't know how to go about replacing the existing user data with new data...for example, if a user needs to replace their password or change their phone number...i've looked all over the web and can't find anything on it...any help is appreciated!
